Added file tcg/optimize.c to hold TCG optimizations. Function tcg_optimize is called from tcg_gen_code_common. It calls other functions performing specific optimizations. Stub for constant folding was added. Signed-off-by: NKirill Batuzov <batuzovk@ispras.ru> Signed-off-by: NBlue Swirl <blauwirbel@gmail.com>

Use stack instead of temp_buf array in CPUState for TCG temps. On Sparc64, stack pointer is not aligned but there is a fixed bias of 2047, so don't try to enforce alignment. Signed-off-by: NBlue Swirl <blauwirbel@gmail.com>

The code for stack allocation for call arguments is way too simplistic to actually work on targets with non-trivial stack allocation policies, e.g. ppc64. We've also already allocated TCG_STATIC_CALL_ARGS_SIZE worth of stack for calls which should be well more than any helper needs. Remove broken dynamic stack allocation code and replace it with an assert. Should dynamic stack allocation ever be needed again, target specific functions should be added. Thanks to Richard Henderson for the analysis. Signed-off-by: NBlue Swirl <blauwirbel@gmail.com>

If an op with dead outputs is not removed, because it has side effects or has multiple output and only one dead, mark the registers as dead instead of saving them. This avoid a few register spills on TCG targets with low register count, especially with div2 and mul2 ops, or when a qemu_ld* result is not used (prefetch emulation for example).

Add support (if CONFIG_DEBUG_TCG is defined) for debugging leakage of temporary variables. Generally any temporaries created by a target while it is translating an instruction should be freed by the end of that instruction; otherwise carefully crafted guest code could cause TCG to run out of temporaries and assert. By calling tcg_check_temp_count() after each instruction we can check that we are not leaking temporaries in this way.

When qemu is configured with --enable-debug-tcg, gcc throws this warning (or error with -Werror): tcg/tcg.c:1030: error: comparison of unsigned expression >= 0 is always true Fix it by removing the >= 0 part. The type cast to 'unsigned' catches negative values of op (which should never happen). This is a modification of Hollis Blanchard's patch.

Some hosts (amd64, ia64) have an ABI that ignores the high bits of the 64-bit register when passing 32-bit arguments. Others require the value to be properly sign-extended for the type. I.e. "int32_t" must be sign-extended and "uint32_t" must be zero-extended to 64-bits. To effect this, extend the "sizemask" parameter to tcg_gen_callN to include the signedness of the type of each parameter. If the tcg target requires it, extend each 32-bit argument into a 64-bit temp and pass that to the function call. This ABI feature is required by sparc64, ppc64 and s390x.

Mirror tcg_out_movi in having a TYPE parameter. This allows x86_64 to perform the move at the proper width, which may elide a REX prefix. Introduce a TCG_TYPE_REG enumerator to represent the "native width" of the host register, and to distinguish the usage from "pointer data" as represented by the existing TCG_TYPE_PTR.
